OMSA Midterm 2 Exam With Complete Solutions Latest Updated Graded 2023/2024. Ways to avoid overfitting - Answer- - Need number of factors to be same order of magnitude as the number of points - Need enough factors to get good fit from real effects and random effects Simplicity - Answer- Simple models are better than complex. When fewer factors exist, less data collection is required -- less chance for including factors that are not significant. Another reason for variable selection! DOE - ...

OMSA Midterm 2 Exam With Complete Solutions Latest Updated Graded 2023/2024. Overfitting - Answer- Number of factors is too close to or larger than number of data points -- fitting to both real effects and random effects. Comes from including too many variables! Ways to avoid overfitting - Answer- - Need number of factors to be same order of magnitude as the number of points - Need enough factors to get good fit from real effects and random effects Simplicity - Answer- Simple models are be...

OMSA Midterm Exam Questions With Complete Solutions Latest Updated 2023/2024. DOE - Answer- systematic method to determine the relationship between factors affecting a process and the output of that process. must make sure either: 1) 2 data sets have same mix 2) break down data into smaller tests that test all factors, not just one. forward selection - Answer- go step by step either narrowing or building a model -- begin with no factors. only allow new factors with p-value 0.1 or lower an...
